Reaction Steps

Overall, 61.31 g of 3-hydroxy-4-iodobenzoic acid are obtained in the form of a white solid. 47 g (150 mmol) of this 3-hydroxy-4-iodobenzoic acid are placed in 300 mL of methanol and 6.13 g (35.6 mmol) of para-toluenesulfonic acid are added. The reaction mixture is heated at 70° C. for 48 hours.— The reaction is stopped by addition of 11 of water. The precipitated product is filtered off and rinsed with water to neutral pH. 37.4 g (76%) of methyl 3-hydroxy-4-iodobenzoate are obtained in the form of a beige-colored powder.
